THE CREAM-COLOURED COURSER.

The CREAM-COLOURED COURSER (Cursorius isabellinus) possesses a slender body and large wings, in which the second quill is longer than the rest; a comparatively short, broadly-rounded tail, composed of from twelve to fourteen feathers; a long, decidedly-curved bill, slender tarsi, and feet furnished with three toes. The thick, soft plumage is of a cream-colour, the upper parts of the body having a reddish and the under side a yellowish tinge; the nape is blueish grey, divided from the rest of the body by a white and a black line commencing at the eyes, and merging into a triangular patch on the nape; the secondaries are sand-yellow, with a black spot near the white tip, and a pale inner web. All the tail-feathers are reddish cream-colour, except two in the centre; these are tipped with white, and striped with black. The eye is brown, the beak blackish, and the foot straw-colour. This species is from eight inches and a half to nine inches long, and nineteen broad; the wing measures six inches, and the tail two inches and a half. The female closely resembles her mate; the young are at once recognised by the mottled and spotted appearance of their somewhat lighter plumage; their primary quills have yellow tips, and the nape is adorned by a whitish stripe bordered by a few black feathers.

The Cream-coloured Courser is a native of Africa, and is met with in Egypt, Nubia, and Abyssinia, being most numerous in the last-mentioned country; it appears in summer along the coast-line from Tangiers to Tripoli, and is seldom found north of the Mediterranean. This bird is one of the rarest visitors to our shores, but three or four specimens have occurred in Great Britain since 1785. Some years ago one was shot in Kent, whilst running over some light land. So little timidity did it exhibit that the gentleman who killed it had time to send for a gun, which did not readily go off, and he in consequence missed his aim. The report frightened the bird away, but after making a turn or two it again settled within a hundred yards, and was dispatched. It was observed to run with incredible swiftness, and at intervals to pick up something from the ground, and was so bold as to render it difficult to make it rise in order to shoot it while on the wing. The note was not like that of a Plover, nor, indeed, to be compared with that of any known bird.

From February to July these Coursers live in pairs, and are usually met with running together over the arid sands of their desert haunts. Travellers tell us that they frequently dart along with such extraordinary rapidity that, like the spokes in a swiftly-turned wheel, their limbs become invisible, so that at a distance they present the appearance of legless bodies darting through the air; if pursued by man, it is not uncommon for them thus to avoid his approach for hours together. If very sorely pressed, they rise upon the wing to a moderate height, and hover for a time before recommencing their wild career. They will allow a rider to come nearer than a man on foot; but even when mounted, it is extremely difficult to get a shot at them, as their many enemies soon render[Pg 11] them very timid. We learn from Bädeker that the eggs of this species are from three to four in number, short and broad, with a sand-coloured glossy shell, marked and dotted with a darker shade. These are deposited in a slight hollow in the ground amongst short grass or stones. We are unacquainted with further particulars respecting the nidification of the Cream-coloured Courser.

THE TROCHILUS, OR CROCODILE WATCHER.

The TROCHILUS, or CROCODILE WATCHER (Hyas Ægyptiacus, or Trochilus), differs in many essential particulars from the above group, to which, however, it is nearly allied. The body of this bird is compact, the neck short, and the head moderately large. The beak is not more than half as long as the head, compressed at its sides, and drawn in at the margins; the upper mandible rises gently from the base, and again curves downwards towards the tip; the lower mandible is straight; the leg is high, bare, and but three-toed; the wing, in which the first quill exceeds the rest in length, is so long, that it extends as far as the tip of the rounded tail. The secondary quills are also unusually developed. In this very beautiful bird, the top of the head, the broad cheek-stripes which unite at the nape, a wide stripe on the breast, and the long slender back-feathers are all black; the eyebrows, throat, gullet, and entire under side are white, shading into pale reddish brown on the sides and breast, and into brownish yellow in the region of the rump; the feathers on the shoulder and upper covers are pale slate-blue or grey; the quills, with the exception of the first (which has only a light border at the base of the outer web) are black in the centre and at the tip, the rest of the feathers being white, thus forming two broad stripes to the wings, which have a very fine appearance when fully spread. The tail-feathers are blueish grey tipped with white, and decorated with a black stripe. The eye is light brown, the beak black, and the foot light grey. The body is about eight inches and a half in length; the wing measures five inches, and the tail two inches and three-quarters. The female is but little smaller than her mate.

Herodotus gives the following quaint account of the supposed strange friendship between this species and the crocodile:—"All other beasts and birds," says that old Greek writer, "avoid the crocodile, but he is at peace with the Trochilus, because he receives benefits from it, for when the crocodile gets out of the water and then opens his jaws, which he does most commonly towards the west, the Trochilus enters his mouth and swallows the leeches which cling to his teeth. The huge beast is so pleased with this service that he never injures the little bird." This well-known account is still current in Egypt, with the addition of another tale traditional among the Nile boatmen concerning this bird, which they call the Zic-zac, in imitation of its call. The crocodile, they say, while reposing on a sandbank, often falls asleep, quite forgetful of his bird friend, who is busy within his large mouth clearing his teeth from their troublesome leech appendages. The Zic-zac, finding the huge door closely shut upon him, gives the crocodile a sharp reminder of his presence by striking his spurs into the mouth of the monster, who immediately sets the prisoner free. The Hyas Ægyptiacus is met with throughout all the country watered by the Nile, and on the shores of all the rivers of Western Africa. It is very doubtful whether any stray specimens have really visited Europe as has been stated; this species, according to our own observations, being strictly stationary in its habits, and only quitting one sandbank for another when compelled to do so by the rising of the water. In all its movements this brisk and pretty little bird displays great ease and rapidity. During the course of its flight, which is never long sustained, it keeps close to the surface of the river, and frequently repeats its shrill whistling cry. Towards every living creature the Trochilus manifests the same utter fearlessness which he exhibits towards his neighbour the crocodile, over and around whose large body he constantly disports himself on the sandbanks, and gleans off the insect parasites that torment him. We can distinctly affirm that we have ourselves repeatedly seen the little creature[Pg 12] performing the tooth-clearing operation the ancients attributed to it, and which many modern writers have declared to be fabulous. Insects of all kinds, worms, small fish, mussels, and, according to some authorities, scraps of meat, and occasionally seeds, form the principal diet of the Crocodile-Watcher. Only once, in spite of all our endeavours, could we discover the carefully-concealed eggs. After many fruitless efforts our attention was attracted whilst looking through a telescope by a pair of birds, one of which was sitting in the sand, and the other running hither and thither in the immediate vicinity. Using every precaution we approached, but were no sooner observed than the brooding parent arose, and after going hurriedly to a short distance, joined its mate, and both together walked slowly from the spot with such a wonderful affectation of indifference, that we were completely taken in, and should not have carried our investigations any further had not a slight unevenness of the ground caught our eye. On removing the sand, two beautiful eggs were brought to light, having a reddish yellow shell, dotted and marked in a variety of ways.
